0.5.0 beta 1 · available now

Big

  • Pages open almost instantly. Budget went from 7 seconds to under half a second, and the Overview from about 1 second to a quarter of one. No more waiting on your own history.
  • Analyse your money with AI in minutes. Export for AI turns any period into one workbook plus a ready prompt. Paste both into the AI you like. Nothing leaves your computer unless you send it.
  • Keep other people’s money out of yours. Note cash you hold for family or friends, and an expense someone paid for you. Your net worth and spending stay honest.

New

  • Know what to do first. A Get set up card walks a new user through five steps and disappears when done.
  • Fix many rows at once. Search “Talabat”, select the rows, set one category on all of them.

Visual

  • The app now looks like Lightning. Our own fonts and logo, cards coloured by what the number means, and a Back button on every detail page.

Fixed

  • Importing a statement takes minutes, not an evening. You answer once per name, not once per row: 17 questions instead of 43 in the sample year.
  • One answer, everywhere. The Overview and Budget now agree on what is left in your plan, and a small “!” says when a figure is an estimate.
  • No more stale prices by surprise. Anything priced more than about two months ago is flagged.

Included in 0.5.0 beta 1

Big

  • Match your bank in one step. Type the balance your bank shows. A small gap is settled with one adjustment, instead of ticking off every line.
  • Track your certificates properly. One portfolio per bank, each CD with its own terms, and interest and maturity cash shown as estimates in your forecast.

New

  • Start over without losing anything. Open a fresh profile and the old one stays exactly as it was.
  • Take just the rows you need. Tick rows and export only those to a CSV.

Visual

  • See your month at a glance. A calendar of your spending and net cash flow, day by day and month by month.
  • One date picker everywhere, Monday to Sunday, usable from the keyboard.

Fixed

  • Dropdowns inside popups can be seen and clicked again.

0.4.0 beta 1 · previous version

Big

  • Lightning on your Windows PC. Your data stays on your computer, in a profile locked with your password and a recovery key.

New

  • Bring in a real statement. Import bank CSVs up to 5 MiB, and review them before anything is posted.
  • Upgrades never risk your data. A verified backup is made first.
  • Report the right build. The version shows in the title bar and Settings.

Visual

  • The answer comes first. Key notes lead with the number, then one line of context.
  • Edit faster. Right-click a register row for Save, History, Cancel and Delete.

Still open

Known gaps

  • An “Other” asset, like a flat, can be counted twice in holdings.
  • Recording something you already owned shows up as a net worth gain.
  • Safe to spend ignores bills due right after payday.
  • Selling everything in a period hides its gain on the Investments tab.
  • Importing your old data and restoring a backup are not in the app yet. Use dummy data for now.
